How To Make Waterproof Speaker Box?

Are you tired of using your regular speaker box and worrying about it getting wet during outdoor activities? It’s time to learn how to make a waterproof speaker box that can withstand any weather conditions.

Making a waterproof speaker box is not as difficult as you may think. First, choose a high-quality speaker that can handle moisture and has a waterproof rating. Next, select a durable and waterproof material to build the box, such as marine-grade plywood or a plastic enclosure. 

Seal all edges and joints with silicone or rubber gaskets to prevent water from entering the box. Finally, test the speaker box thoroughly to ensure it can withstand water exposure.

With these simple steps, you can enjoy your music outdoors without worrying about damaging your speakers. In this article, we’ll go over everything you need to know to make a waterproof speaker box that will keep your tunes going no matter the weather.

Materials Needed  to make waterproof speaker box

As someone who has made several waterproof speaker boxes for outdoor use, I can tell you that the materials you use can make all the difference. Here are the materials that I typically use to make a waterproof speaker box:

Speaker Components

  • Speaker Drivers
  • Crossovers
  • Terminal Cups
  • Wires

Woodworking Materials

  • Plywood or MDF board
  • Table saw or circular saw
  • Jigsaw or scroll saw
  • Drill with different-sized drill bits
  • Clamps
  • Wood glue
  • Screws

Waterproofing Materials

  • Silicone sealant
  • Liquid rubber coating
  • Waterproofing spray
  • Weatherstripping
  • Gasket material

Miscellaneous Items

  • Sandpaper or sanding sponge
  • Paint or wood stain
  • Paintbrushes or foam rollers
  • Tape measure
  • Pencil or marker
  • Safety glasses and gloves

When it comes to speaker components, it’s important to choose high-quality components that are designed to handle outdoor environments. You don’t want to spend all that time building a waterproof speaker box only to have the components fail due to exposure to moisture.

For woodworking materials, I prefer to use ¾ inch thick plywood or MDF board. These materials are strong and durable, and they hold up well to the elements. 

A table saw or circular saw is essential for cutting the wood to the correct size, while a jigsaw or scroll saw is useful for cutting out speaker openings and other shapes.

Waterproofing materials are crucial for ensuring that your speaker box is truly waterproof. Silicone sealant is great for sealing gaps and joints, while liquid rubber coating can be applied to the entire box for added protection. 

Waterproofing spray can also be used to protect the wood from moisture while weatherstripping and gasket material can help seal the speaker components to the box.

Preparation  to make waterproof speaker box

Before beginning the process of building a waterproof speaker box, it is important to prepare all the necessary materials. This will ensure that the process is smooth and efficient. Here are the steps I followed to prepare for building my own waterproof speaker box.

Gather Materials:

The first step in preparation was to gather all the necessary materials. I researched the best materials for a waterproof speaker box and made a list of them. Some of the materials I needed included marine-grade plywood, silicone sealant, marine carpet, and waterproof speaker wire. I made sure to purchase high-quality materials to ensure the durability and effectiveness of the speaker box.

Measure and Cut:

After gathering all the materials, I measured and cut the marine-grade plywood to the appropriate size. I used a circular saw to make precise cuts and followed the dimensions of my speaker design. It was important to measure multiple times to ensure accuracy and avoid mistakes.

Sand and Smooth Edges:

Once the plywood was cut to the correct size, I sanded and smoothed the edges using sandpaper. This helped to avoid splinters and create a clean finish.

Plan for Waterproofing:

I then planned out the waterproofing elements I would need to add to the speaker box. This included adding silicone sealant to all seams and edges to prevent water from seeping in. I also planned to add marine carpet to the interior of the box to absorb any moisture.

Building the Speaker Box

Building a waterproof speaker box can be a fun and rewarding project, but it does require some basic woodworking skills and tools. In this section, I’ll share my experience on how I built my own speaker box, step by step.

Materials Needed:

  • MDF board
  • Saw
  • Screwdriver
  • Wood glue
  • Screws
  • Speaker driver
  • Speaker grill
  • Speaker wire
  • Speaker box insulation

Step 1: Design and Cut the Pieces 

I started by designing the box on paper to ensure that I had the correct dimensions and angles. Then, I cut the MDF board into pieces according to my design using a saw.

Step 2: Assemble the Pieces 

Next, I applied wood glue to the edges of the pieces and screwed them together. I ensured that the box was square and even by using a carpenter’s square.

Step 3: Install the Speaker Driver 

I marked and drilled a hole in the centre of one of the side panels for the speaker driver. Then, I mounted the speaker driver using screws.

Step 4: Install the Speaker Grill 

I attached the speaker grill to the front of the box using screws. This would protect the speaker driver from damage.

Step 5: Install the Speaker Wire and Box Insulation 

I connected the speaker wire to the speaker driver and then insulated the box using speaker box insulation to improve the sound quality.

By following these steps, I was able to build a solid and sturdy speaker box that could withstand moisture and water. However, I still needed to add waterproofing elements to ensure that the box was completely waterproof, which will be discussed in the next section.

Adding Waterproofing Elements

Now that the speaker box is built, the next step is to make it waterproof. I found that adding waterproofing elements can be done relatively easily and can make a huge difference in the longevity and effectiveness of the speaker box. Here’s how I did it:

  1. Sealing the Box: The first step in waterproofing the speaker box is to seal it. I used a silicone sealant to cover all of the seams and edges of the box. This helped to prevent any water from seeping into the box and causing damage to the speakers.
  2. Coating the Speaker Cone: Another important step is to coat the speaker cone with a waterproofing material. I used a spray-on waterproofing product that I found at a hardware store. I applied several coats to ensure that the speaker cone was completely covered.
  3. Installing a Waterproof Membrane: In addition to sealing the box and coating the speaker cone, I also installed a waterproof membrane inside the box. This membrane helped to protect the speakers from any moisture that might enter the box. I used a sheet of waterproof material that I cut to size and then attached to the inside of the box with adhesive.
  4. Testing the Waterproofing: After adding all of the waterproofing elements, it’s important to test the speaker box to ensure that it is truly waterproof. I tested the box by placing it in a basin of water for a few hours to see if any water seeped inside. Luckily, my waterproofing efforts paid off, and the speaker box remained dry.

Testing the Speaker Box

Once the waterproof speaker box has been built, it’s essential to test its effectiveness to ensure that it can withstand any potential water damage. Here’s how I tested my waterproof speaker box:

Waterproof Testing Materials 

To test the waterproofing of the speaker box, I gathered a few materials, including a bucket of water, a towel, and a portable music player.

Test Steps

  1. Filling the bucket with water I filled the bucket with enough water to submerge the speaker box.
  2. Placing the speaker box in the bucket Next, I placed the speaker box into the bucket of water. I made sure that the speaker box was fully submerged.
  3. Playing music I turned on the music player and played music at a medium volume level. I let the music play for about 30 minutes.
  4. Removing the speaker box from the water After 30 minutes, I removed the speaker box from the water and dried it off with a towel.
  5. Testing sound quality I then tested the sound quality of the speaker box. The sound quality was just as good as it was before the testing process.
